Daoist Yin-Yang Manual

Ju Yeonhwa couldn't fall into a deep sleep.

As the night deepened, her mind grew hotter and hotter.

That scene she had peeked at through the crack in the door.

The sight of Jin Seoyun and Hong Seorin, the person she held closest, entwined like beasts, kept replaying in her mind.

Beastly moans, Hong Seorin's face contorted in pleasure.

The sounds of sweat, saliva, and bodily fluids drenching each other on the bed. All of it remained vividly, so clearly.

Ju Yeonhwa rubbed her cheek against the pillow, her body twitching.

'It was... vulgar... so... embarrassing...'

They had relied on each other amidst the turbulent currents of the imperial palace.

The only person with whom she could share laughter and her true feelings.

That very person, that night, had her mouth open, her legs spread, twisting her own hips to receive the man's penis.

The obscene words she had heard then kept echoing in her ears.

'Pussy... dick... cum...'

Words she had never uttered in her entire life.

Obscene words she hadn't even heard in the imperial education hall as a child floated through her mind.

"Pussy..."

Ju Yeonhwa swallowed her breath.

Just uttering that single word made her chest tighten and her thighs tingle.

'Ugh, my crotch is so itchy!'

That man. Jin Seoyun.

His face, his hands, his muscles. And the dick that had been thrusting into Hong Seorin.

'...Why do I keep thinking about that...'

Ju Yeonhwa lowered her head. But her mind was already filled with Jin Seoyun's body.

Slowly, very slowly. She put her hand between her thighs.

It was an act she had never done before.

A life lived suppressed by countless taboos and education, told that as a princess, she must never do such things.

A line she had never crossed within that framework.

'...Because no one is here.'

Whispering an excuse to herself, her fingers slowly pushed aside her underwear.

At that moment, a hot, slippery sensation enveloped her fingertips.

"Haaht..."

A moan involuntarily escaped her lips.

She stopped her hand in surprise, but her underwear was already wet, and her insides were throbbing.

When she closed her eyes, the scene reappeared.

The scene of him roughly ravishing Hong Seorin.

'...If I... were to do it, would I become like that...?'

At that thought, her fingertips moved on their own. A little deeper, a little stronger.

Moist flesh clung to her fingers, wrapping around them softly. As she spread her legs, the heat emanating from between her thighs spread more intensely.

Hong Seorin, the person she trusted and relied on the most.

Her man.

Recalling Jin Seoyun, she stroked herself down below.

"Aheung...!"

Even with just a light touch, a tingle ran down her spine. Her lower abdomen felt ticklish, her breath quickened, and her chest dropped.

'Imagining someone else's man... and masturbating...'

Her heart pounded wildly at that realization.

But she didn't dislike that sensation.

No, rather...

It was thrilling.

Under the full moon in the night sky, the surroundings were quiet, but the beastly sounds of copulation in the silence were too explicit.

She was gripping a rough wooden pillar with both hands, her legs spread, pushing her hips far back.

-Jjigeok! Jjigeoeok! Paang! Jjigeok!

"Ang...! Dick... I love dick...! Joaang...♡"

The sight of her trembling thighs and straining her toes,

showed just how stimulating this situation was.

'Should I... start training her asshole too?'

I reached out and grabbed her firm buttocks. Then I slapped her round, luscious ass with my palm.

-Chalsak!

"Ang...♡"

Along with a seductive moan, her pink anus twitched and wiggled cutely.

I dipped my finger in the vaginal fluid that had flowed from her pussy, then, after applying some lube, slowly rubbed it over her anus.

-Jjeugeok... Jjeut... Jjeueuk...

"Eueung... Ha-eu...!"

Each time my fingertips slid in a circle, rubbing, Hong Seorin's buttock muscles twitched and tightened, and she gripped the pillar she held with both hands even tighter.

"Just touching you here makes you tremble like this... You have a talent for it, don't you?"

I whispered and slowly pushed my finger into her anus. The moist, wet pink hole wrapped around my finger and swallowed it inside.

"Ogo-ok...♡"

Her leaked moan. With her heels pressed firmly into the ground as if stamping, her knees trembled, and her waist quivered.

"Oh, you came?"

"Eut... Haak...! No... That, there... it's really weird...!"

"It's not weird, it's getting good, isn't it?"

I slowly extended two fingers and carefully rubbed inside her anus.

As the two fingers slowly circled, widening the hole, her anus quivered and reflexively tightened.

"Haaht... No... no... it keeps opening..."

"Relax. It's supposed to open like that."

I bent my finger once more and pushed up the inside of her anus.

As the stimulation spread beyond the thin wall touching her pussy, Hong Seorin gasped and arched her back.

"Ang... Haaang... I don't know...! My pussy and... my asshole... are being poked together...♡"

I slowly spread my fingers.

-Jjeut... Jjeugeoeok...

With a small sound, her anus slowly began to open. The tight muscles relaxed, and a hot sensation was felt from within.

"If we open it up little by little like this, anything will fit now, won't it?"

"Haa... Haak...! Don't... don't say things like that... I'm getting weird...!"

I widened the space between my fingers and took out anal beads from my inventory window. Then, I generously applied oil to the beads,

and slowly placed the smallest bead at the entrance of her anus.

-Jjeut...

"Eut... Haang...♡ What's that... Is it something weird...?"

"It's not weird... It's something that will make your asshole obscene, my lady."

I gently pressed the first bead. Her opened anus tightened as if swallowing the bead.

-Jjeueuk...

"Haaht...! It's... in...♡"

"It's just the beginning."

The second, the third...

One after another, increasingly thicker beads were inserted into her asshole.

Each time, her waist twitched, and her hands gripping the pillar tightened.

"Hiaaaht...! Ah-heut...! That... no...! It keeps going in...!"

After inserting the fourth bead, I left the remaining tail part dangling outside her anus and gently pulled.

-Jjeureureuk...

"Kyaak...! No...! If it comes out from inside... it'll be weird... I'll get weird...!"

"You like it? Then I'll continue."

I slowly pulled out the anal beads, watching her elastic anus contract and then open again with each bead.

"Wooeut... Heueuk... Feeling it... with my asshole... it's so weird..."

Drooling saliva, trembling legs, a face on the verge of climax.

Hong Seorin had already swallowed the beads deep into her anus, and was instinctively extracting pleasure, her toes curled.

I repeatedly pushed the beads all the way into her anus, then pulled them out slightly, then pushed them in again.

-Jjeureureuk... Jjuuk... Puk.

Then, I turned my head slightly and glanced into the forest.

'She came again today.'

Silver-white hair. Golden eyes faintly gleaming in the moonlight.

It had been happening for several days now. Ju Yeonhwa, who unfailingly held her breath and peeked whenever I fucked Hong Seorin.

At first, it was simple voyeurism. But at some point, her hand slowly slid down to her thigh, beneath her skirt, and was rubbing her pussy.

'Masturbating while voyeuristically watching. Contrary to her appearance, is she very interested in this sort of thing?'

Since that day, she had been secretly watching, voyeuristically.

So today, I showed her quite openly, as if to say, "Look."

I gripped Hong Seorin's waist more fiercely, pulled her buttocks apart, and fully exposed her pink anus. Then, I slowly inserted and withdrew the anal beads one by one into her tightly clenching anus, repeatedly.

-Jjeueuk... Jjeueuk... Ssuuk!

Each time I inserted them, there was a squelching sound from her anus, and Hong Seorin's vulgar moans leaked through the gaps.

"Hiaaaak...♡ Nooo...! It's all going... in...!"

Her spine convulsed, and her hands gripping the pillar tightened as if tearing at it. At that moment, I subtly shifted my gaze to Ju Yeonhwa.

She was biting her lip, engrossed in masturbation. Her expression looked like that of someone addicted to drugs.

'If this goes well, she'll come over on her own, won't she?'

I chuckled. Then I turned my head back, gripped the anal beads inserted into Hong Seorin's anus with one hand, and twisted them.

-Jjeueup! Jjeureureuk... Jjilgeok!

"Aang...! Eung-hik...! Nooo... At the same time... This... I'm going crazy...!"

With my other hand, which was holding her buttocks, I slapped Hong Seorin's ass hard. Chalsak! Along with the sound, flesh jiggled, skin reddened, and pussy juice flowed out between them.

-Pushut...! Pushut...!

Her body had become a completely aroused female, and her lips were spewing squelching moans as she swallowed pleasure with her asshole.

I deliberately lowered my voice and whispered. So that the princess hidden behind the tree, beyond the pillar, could hear.

"My lady, your expression and moans are too vulgar. Anyone would think you're a street whore."

And then, I slowly began to twist and pull out the anal beads that were embedded in her anus.

-Jjeugeoeok...!

"Haat... No... no...! If it comes out... it'll be weird... Haaang...!"

Each brief moment a bead came out, her anus twitched and tightened. Inside, it was lukewarm and wet,

and Hong Seorin trembled at the waist, arching her head back.

I slowly spread her buttocks and looked into the slightly parted, faintly trembling pink hole between them.

The slightly parted edge of her anus was already wet and glistening with vaginal fluid and oil, and it twitched as if waiting for my dick, revealing its inside.

"Your dick is ready to go in. Now... anal sex, begins."

-Jjigeoeoeok!

As the glans pushed in, her anus tightened as if screaming, then its inside opened up.

"Haaaaaaak♡ Diiick...!! Thrust innn... My asshole is tearinggg...!"

Hong Seorin's upper body swayed and clung to the pillar. Her entire body convulsed, and her breath caught in her throat as if cut off.

"Oh..."

It was alienly narrow and hot.

Among all the women I had fucked so far, a rear end with this level of elasticity and pressure was rare.

The sensation of it slowly tightening from within, completely different from a vagina, a helpless resistance overlapping with pleasure.

I gripped her buttocks and slowly thrust in, swaying my hips.

Then, the inside began to clench incredibly tightly.

"Heueuk... Haaang...! Oh, Owaaht...! My dick... is getting bigger... inside...!"

Hong Seorin whimpered and pushed her buttocks back. Her anus twitched in rhythm with the dick, and vibrations seemed to spread even into her vagina.

"My lady's anus... it's truly amazing. This... makes me want to put it in every day."

I pulled my hips back slightly, then roughly thrust in again.

-Jjigeok, Jjigeok, Jjigeok!

"Eung-hit...! Hek, Aang...♡"

Hong Seorin's anus tightened from within, swallowing the dick.

A dense pressure, completely different from a vagina. Rather, it felt as if the dick was slowly being squeezed out, twisting and tightening from deep within her body.

"Hoo... It's really... narrow and hot. Your anus, my lady... it's a masturbation device for squeezing out cum."

I exhaled and gripped her waist even tighter.

And I pushed.

-Peok! Peoeok! Peok, Peoeok!

"Uwaaaang...! Heeut...! Eung-hiiik...!"

I reached out and wrapped my hand around her thigh from the inside. Then I firmly pressed the thin area between her anus and vagina.

"Hiiik...! No...! There... if you press there... my asshole... tingles...!"

"You like it, don't you?"

"Haang... It's true...! I... I've become weird...!"

I twisted my hips as if to rotate, thrusting my dick in, then pressed the inside of her thigh to stimulate both her vagina and anus simultaneously.

She lifted one leg, swallowing the dick deeper.

"Haak... Dick... No... I'm going crazy...!! I'm coming... through my asshole...!! Cum, cummm...!"

And at that moment-

Her anus strongly contracted. It tightened impossibly, clenching my dick as if devouring it.

"Keueut...!"

I gritted my teeth and placed my hand more firmly on her trembling waist.

And then, I ejaculated just like that.

-Byureureut! Byureureureureut!

Sticky cum was sprayed deep inside her clenching anus.

"Ogo-o-ok...♡"

A single word escaped Hong Seorin's lips. Unfocused eyes, a body drenched in sweat, and slightly parted lips with drooling saliva.

Her anus was still tightly wrapped around my dick, twitching,

and her trembling body remained immersed in the afterglow of climax even after ejaculation.

I slowly stroked her back, leaning close to her lips and whispering.

"...Now your asshole is my property, so take good care of it. Understood?"

I slowly withdrew my hips and smiled, watching the cum dripping from her squelching wet anus.

Instead of answering, she quivered her buttocks between her trembling legs, then curled the corners of her lips as if sticking out her tongue-

-Pushuuuuut.........!

"Eung-hii-hit...♡"
